Government health officials say trans fats are a public health concern. They're considered the worst kind of fat for your heart because they can raise bad cholesterol. "We could save about 7,000 lives and prevent about 20,000 heart attacks in this country every year. That why we think this is an important step," said FDA Commissioner Dr. Margaret Hamburg.
New York was the first city to ban trans fats in restaurants seven years ago. Since then many other cities and states have done the same.Ten fast food chains have also eliminated trans fats entirely.
